The whorls on the spire are sloping, scarcely concave in the upper part, convex in the lower.

The siphonal canal is short, open and barely notched.

The posterior sinus is deep, rather narrow, separated from the suture by a distance equal to its width, then convex, with an anterior shallow sinus at the base of the siphonal canal.

The sculpture of the first two whorls is closely, regularly, validly, axially costulate, the rest rudely ribbed in the anterior two-thirds.

The spiral incisions ai'e deep, irregularly slightly wavy, about 8 in the penultimate whorl, and 20 in the body whorl, nearly equidistant, in places alternately fine and wide.
